Abstract: A multiple peripheral component interconnect (PCI) agent integrated circuit device for connecting to an external PCI bus. In one embodiment, the present multiple PCI agent integrated circuit device includes, an integrated circuit which is adapted to be coupled to an external PCI bus. The integrated circuit includes an internal PCI bus built in. The internal PCI bus is adapted to transmit data signals thereon, and is further adapted to couple to the external PCI bus via a connector. A plurality of PCI agents are built into the integrated circuit, wherein each of the plurality of PCI agents are capable of performing an independent function. Each of the plurality of PCI agents are coupled to the internal PCI bus. A predictive arbiter is built into the integrated circuit and is coupled to both the internal PCI bus and to the plurality of PCI agents. The predictive arbiter arbitrates between the PCI agents for ownership of the internal PCI bus.

Abstract: A light-weight, multi-purpose light-duty yard tool made with a small sheet metal blade part shaped like a truncated triangle with the widest part at the front and the narrow edge at the heel or rear end. The front side portions are slightly cupped as is the wide front edge, to enable use as a shovel. The front edge has cutouts with sharpened edges providing raking tines to be used as a pushing cutting member. The forward portions of the side edges are sharpened, enabling use as an edging or slicing tool, while the rear portions of the side edges are flanged for strength. A tang piece, riveted to the heel part of the blade, provides a device for attaching the blade to a lightweight wood handle of medium length. The tool length preferrable is the distance from the users waist to the ground.

Abstract: Electric power is generated by power generators submerged to a substantial depth in a body of moving water. The generators are housed in bodies configured to create a large pressure differential across a conduit. This generates a rapid, substantial flow of water through a conduit in which is located an impeller which is driven to energize a generator to thereby generate electricity.

Abstract: There is disclosed an awning which is adapted to be supported by a pair of spaced members on which two wheels of a motor vehicle are driven. Support projections incline upwardly from the member and removeably receive a plurality of elongate supports. The elongate supports comprise a pair of spaced upstanding tubular members on which a fabric canopy is supported. The awning can be quickly erected and dismantled and makes no contact with the motor vehicle except on the underside of the wheels thereof.

Abstract: This invention relates to a process for hydrometallurgical treatment of concentrates of sulphides of copper, nickel, cobalt, lead and iron and copper-containing mattes. A first embodiment of the process includes subjecting a finely ground slurry of a sulphide concentrate to an oxidation leach at elevated temperature and pressure in the presence of an oxygen-bearing gas to preferentially leach cobalt and nickel and to convert galena to lead sulphate. The reaction mixture is heated to a further elevated temperature, in the absence of oxygen, to convert a portion of chalcopyrite to insoluble simple copper sulphides and ferrous sulphate solution and to decompose complex insoluble ferric compounds. The resulting mixture is subjected to differential flotation whereby a lead concentrate and a copper concentrate are obtained.

Abstract: A process for the treatment of zinc plant residue formed on leaching zinc calcine with sulphuric acid in which the residue is leached in a first leaching step with a sulphuric acid solution at atmospheric pressure, and a temperature above about 60.degree.C, in the presence of excess zinc sulphide reductant whereby ferric iron in the residue is reduced to the ferrous state, thereby forming a zinc sulphate solution containing excess acid, ferrous iron and other dissolved impurities such as germanium, indium, gallium, antimony and arsenic nd a mixture of solids containing undigested zinc residue, lead residue, and unreacted zinc sulphide. Clarified solution is separated, preferably by thickening, from the mixture of solids. The mixture of solids is leached in a second residue leaching step at atmospheric pressure and at a temperature above about 60.degree.
